paragraph provides the design criteria

unique to VdS Approval listing.

VdS Listing Design Criteria

• Wet-pipe systems only

General

Description

The TYCO FASTFLEX Model FB Flex-

ible Braided Hose is a unique sprinkler

drop assembly comprised of a stainless

steel exible hose a swivel inlet nipple,

a sprinkler reducer, and lightweight

ceiling bracket components. (Refer to

Figure 1.)

The FASTFLEX Model FB Flexible

Braided Hose can be installed in false

ceilings without cutting and thread-

ing pipes associated with installing a

drop, arm-over, and elbow. It provides

easier maneuverability around ducts

and trays in congested spaces and for

unusual ceiling types and curved plas-

terboard ceilings. The FASTFLEX Model

FB Flexible Braided Hose makes it pos-

sible to test and charge the system with

water before the ceiling grid is installed.

Once the ceiling grid is in position, the

hoses can be reshaped to suit the nal

sprinkler location without draining the

system.

The FASTFLEX Model FB Flexible

Braided Hose hoses are for use on wet

pipe sprinkler systems only.

NOTICE

The TYCO FASTFLEX Model FB Flexible

Braided Hose ﬂexible sprinkler hoses

described herein must be installed

and maintained in compliance with

this document and with the applicable

standards recognized by the Approval

agency, in addition to the standards of

any other authorities having jurisdiction.

Failure to do so may impair the perfor-

mance of these devices.

The owner is responsible for main-

taining their fire protection system

and devices in proper operating con-

dition. Contact the installing contrac-

tor or product manufacturer with any

questions.

Approved Ceiling Systems

FASTFLEX Model FB Flexible Braided

Hose is approved for use only in the

following manufacturers suspended

VdS Friction Loss

For compensation of pressure

loss, the nominal assembly length

is to be multiplied by 10. The re-

sulting length will provide pressure

drop in equivalent length DN25

(33,7 x 3,25 mm) metal tube per EN

10255.

• Add 2,3 m when using a 90° sprin-

kler reducer.

Installation

The TYCO FASTFLEX Model FB

Flexible Braided Hose, as shown in

Figure 1, must be installed in accor-

dance with this section.

NOTICE

Flexible Braided Hoses are intended

only to connect sprinklers directly to

system piping (refer to Figure 1). Flex-

ible Hoses cannot be joined together

to form longer hoses. Joining Flexible

Hoses together creates an assembly

with unknown performance that has

not been accounted for in system cal-

culations or safe product performance.

Step 1. Review the Design Criteria

section that applies to the approval

agency recognized by the authority

having jurisdiction, as well as Figure 3

that provides Installation Guidance.

Step 2. Determine approximately where

the sprinkler will be located. Mount the

End Brackets to the Support Bar then

slide the End Brackets over the ceiling

grid T-bars. The sprinkler should be

located as close to the center of the dis-

tance between the ceiling grid T-bars

as possible.

Step 3. Hand-tighten the Wings Screws

and the Hex Screws on the End Brack-

ets securing the Support Bar.

Step 4. Attach the Swivel Inlet Nipple

to the Branchline Fitting outlet. (Refer

to Figure 1.) Apply the wrench directly

to the Swivel Inlet Nipple and tighten to

the maximum torque of 35 Nm.

Step 5. Attach the sprinkler to the

Sprinkler Reducer. Place a wrench on

the Sprinkler Reducer to counteract

the tightening torque of the sprinkler

and torque the sprinkler to the recom-

mended torque setting. Refer to the

sprinkler manufacturer’s sprinkler data

sheet for appropriate sprinkler torque

setting, sprinkler wrench, and other

guidance.

Step 6. Bend the Flexible Hose and

place the Sprinkler Reducer to where

the sprinkler will be located. The hose

arc should not be twisted, and the arc

should be as large and smooth as pos-

sible. (Refer to Figures 2 and 3.)

NOTICE

For minimum bend criteria, refer to the

Design Criteria section that applies to

the approval agency recognized by the

authority having jurisdiction.

A bend radius smaller than pro-

vided by the minimum bend criteria

may adversely effect the friction loss

speciﬁcations stated by the approval

laboratory.

Step 7. Slide the Reducer Bracket over

the Sprinkler Reducer end of the Flex-

ible Sprinkler Hose and clip over the

Support Bar. Hand-tighten the fastener

on the Reducer Bracket securing the

Reducer Bracket to the Support Bar.

Ensure that the Reducer Bracket fas-

tener is secured to the at surface of

the Sprinkler Reducer.

Step 8. After tightening the Reducer

Bracket fastener, verify that the sprin-

kler is properly located in accordance

with the manufacturer’s instructions.

If not in the proper location, adjust its

position as necessary.

Step 9. Once the sprinkler is in the

proper location, torque all hardware as

follows:
